The idea is appreciated. I got it working fairly happily once I got the
cdrom connected and had something to do IPL from.

Like a part number? :) 11H2534, it's an IBM GXT150M card. 1280x1024
apparently, 13W3.

I also have a 75X5887 "PS/2 XGA Display Adapter/A" that came out of a 486,
but I'm not sure it'll work in an rs6k. I'm happy with the GXT150M for now
though. :)

I also pulled a 66G1080 SCSI A/16 card, typical external IBM SCSI port and
50 pin internal... I wonder if that will work in here. Once again,
guessing it won't, and it seems to not handle boot drives >1G on the PS/2.

I'm using a laplink-type cable, so I'm not sure what it does. I use these
for the Suns all the time (which is why I had them around). Will have to
look into getting a full hardware adapter and a straight cable.

Thanks for the pointers and such.
